Definitions
- Sensor unit and method for sensing a blood related parameter and system including such a sensor unit
- the invention concerns a sensor unit for sensing a blood related parameter in a bloodstream of a human or an animal. It also concerns a method for monitoring the function of a bloodstream access device and a blood parameter sensor system including such a sensor unit.
- US-A-5 120 313 discloses a method for measuring blood pressure in an animal or human using a percutaneous access port .
- This access port includes a base assembly which is intended to be implanted into the animal or human and comprises an inlet port which is adapted to be connected to a selected organ in order to provide communication with a fluid chamber inside the base assembly.
- a transducer inside the fluid chamber of the base assembly is adapted to detect the pressure of the fluid so as to provide a signal indicative of the blood pressure of the human or the animal.
- the described arrangement is equipped with a pump for continuously flushing the system including a catheter for connection to the bloodstream of the human or the animal in order to prevent formation of blood clots. Altogether the described arrangement is an insecure, complicated, limited and expensive solution which appears to be mainly intended for use in animals in connection with medical research.
- the inventive sensor unit provides for easy application in or on a bloodstream access device and guarantees that the sensor element is operative with respect of a continuous blood flow, thus guaranteeing that sensing of the blood related parameter is carried out accurately.
- a bloodstream access device which preferably is implanted for permanent use. Normally such devices are implanted so as to allow blood treatment such as blood filtering in case of patients with a renal failure diagnosis. According to this aspect of the invention such a device is used as part of the sensor system besides its normal use for blood treatment.
- a preferred bloodstream access device is previously known from WO 99/20338 (Hemapure AB) . It is preferred that a lid member being included in the sensor unit of the present invention is adapted to be applied to a bloodstream access device according to that document in a manner which is thoroughly described therein.
- Allowing a continuous blood flow during operation of the sensor element avoids formation of clots etc. and contributes to the sensor unit according to the invention being a long life solution.
- An inventive method provides for monitoring the function of the bloodstream access device.
- the blood temperature is sensed in a channel which allows a continuous blood flow passing between an artery side and a vein side of the bloodstream access device.
- the sensed value is used as an indication of the blood flow through the bloodstream access device.
- Low flow and low temperature might indicate malfunction of the access device for various reasons and should at least trigger a control of the device by skilled personnel .
- Fig. la shows a bloodstream access device for use in connection with a system according to the invention
- Figs. 2a and 2b show an arrangement including a bloodstream access device with attached sensor unit according to the invention
- Fig. 3a and 3b show an alternative sensor unit
- Fig. 4 shows a system including an inventive sensor unit in respect of a human.
- a bloodstream access device 1 having nipples 2 and 2' for connection to an artery and a vein of a human or an animal.
- Channels 3 and 3' interconnect the nipples with a flat or curved interface surface 4 which is intended for connection to a connection device belonging to an external circuit.
- a connection device belonging to an external circuit.
- Such a circuit could include an artificial kidney.
- the interface is co-operating with a lid between blood treatments, said lid including a channel for allowing a continuous flow between the artery and the vein side through the channels 3 and 3' .
- the device 1 is intended for permanent implantation into a human or an animal and includes means for allowing ingrowth of body tissue for stabilising purposes.
- the bloodstream access device 1 in Fig. 1 is shown in a view from the right in Fig. 1 carrying a sensor unit 5 which is shown in a section.
- the sensor unit 5 co-operates with the bloodstream access device to that extent that it provides sealing co-operation between a sealing surface 6 and the surface of the interface 4 of the bloodstream access device 1.
- the sensor unit 5 is thus positioned and fixed on the bloodstream access device in a manner which is described in the above-mentioned WO document.
- the sensor unit 5 has a channel portion 7 which is intended to interconnect the channels 3 and 3' of the bloodstream access device 1 so as to allow a continuous blood flow through the device with the applied sensor unit 5.
- the channel 7 is limited by a wall including a sensor element 8 comprising a sensor layer 9 which comprises the inner wall portion of that part of the channel portion 7.
- the sensor element 8 includes a translucent protective layer 10 which protects the sensor layer 9 from being affected from outside mechanical influences as well as, in certain applications, provides a certain thermal insulation so as not to cool down the blood streaming through the channel 7.
- the sensor layer 9 includes preferably liquid crystals which are sensitive to the parameter which at present is intended to be sensed. It may thus for example be temperature sensitive or sensitive to a defined substance in the bloodstream such as insulin or glucose. As is per se known, the sensor layer may be of a kind which changes colour so as provide a visual indication of the parameter level, be it temperature, concentration etc., of the blood being present inside the channel 7.
- Temperature indication may in turn be used as a measurement of the flow through the channel 7. I.e. in principle, high flow results in high temperature; low flow results in lower temperature. Flow indication in turn may be used for monitoring the function of the bloodstream access device and absence of clots etc. However, temperature indication could also be used for monitoring the certain ill-health conditions of the patient. An ideal temperature might be for example 35°C and higher or lower temperatures might indicate some kind of problem.
- the indication could be used as a warning or as a trigger for introducing medication into the patient.
- the sensor layer includes sensor elements that are indicative of the concentration of a specific substance in the bloodstream, this may be indicated similarly, that is with liquid crystals which have the capability to change colour or in any other per se known manner.
- Fig. 2b shows the bloodstream access device 1 from above with a fastened sensor unit 5.
- the sensor element 8 is shown as an oblong element in the centre of the sensor unit 5.
- the sensor element 8 is surrounded by a surface 20 having a colour scale.
- easy comparison with the present colour of the sensor element 8 is enabled. This makes it possible to have a quick indication on the temperature and thus the function of the device 1 or, at occasions, the concentration level etc. prevailing inside channel 7.
- a second embodiment of a sensor unit 11 is shown in fig 3a.
- the sensor unit is provided with snap wings 14, and pressing portions 15 on holding means 17. Further, locking elements or shoulders 18 are used for positioning the sensor unit 11 on a bloodstream access device 1 (Fig. 1) .
- An oblong sensor element 16 is positioned centrally and with an acute angle with respect to a longitudinal axis of the sensor unit 11. At the sides of the sensor element 16, there are indicated two areas 19 which may be coloured in scales so as to provide easy indication of flow, temperature, concentration etc. etc.
- Fig. 3b shows the sensor unit 11 in a longitudinal section wherein the curved sensor element 16 contributes to limit a channel 13, which corresponds to the channel 7 of the sensor unit 5 in Fig. 2a.
- the invention may be modified further and for example the sensor units 5 and 11, which in practice are lid members for co-operation with the bloodstream access device, may be connected to outside equipment for indicating sensed temperature, flow concentration etc.
- This is indicated in fig 4, which shows a system including an inventive sensor unit in respect of a human.
- the lid member may be connected, for example over an electric wire 21 or wireless, with a wrist carried indicator 22 resembling a wrist-watch.
- an inventive sensor unit may be connected to an insulin pump 23 for introducing insulin into the body of the patient.
- a simple external device may be a warning indicator such as a buzzer, a beeper or a lamp, indicating malfunction or parameter levels below a predetermined value.
- blood temperature, blood flow, blood-pressure, level of biochemical substances such as glucose, insulin, urea may be subject to being sensed by adapted sensor elements of a sensor unit according to the invention. Further modifications may include other per se known sensor elements; use in connection with other types of bloodstream access devices; and connections to other kinds of indicators and external equipment .
